AnIn1 Function [511]
Sets the function for Analogue input 1. Scale and range are
defined by AnIn1 Advanced settings [513].
Communication information
Adding analogue inputs
If more than one analogue input is set to the same function,
the values of the inputs can be added together. In the
following examples we assume that Process Source [321] is
set to Speed.
Example 1: Add signals with different weight (fine tuning).
Signal on AnIn1 = 10 mA
Signal on AnIn2 = 5 mA
[511] AnIn1 Function = Process Ref.
[512] AnIn1 Setup = 4-20 mA
[5134] AnIn1 Function Min = Min (0 rpm)
[5136] AnIn1 Function Max = Max (1500 rpm)
[5138] AnIn1 Operation = Add+
[514] AnIn2 Function = Process Ref.
[515] AnIn2 Setup = 4-20 mA
[5164] AnIn2 Function Min = Min (0 rpm)
[5166] AnIn2 Function Max = User defined
[5167] AnIn2 Value Max = 300 rpm
[5168] AnIn2 Operation = Add+
Calculation:
AnIn1 = (10-4) / (20-4) x (1500-0) + 0 = 562.5 rpm
AnIn2 = (5-4) / (20-4) x (300-0) + 0 = 18.75 rpm
The actual process reference will be:
+562.5 + 18.75 = 581 rpm
Analogue Input Selection via Digital Inputs:
When two different external Reference signals are used,
e.g. 4-20mA signal from control centre and a 0-10 V locally
mounted potentiometer, it is possible to switch between
these two different analogue input signals via a Digital Input
set to “AnIn Select”.
AnIn1 is 4-20 mA
AnIn2 is 0-10 V
DigIn3 is controlling the AnIn selection; HIGH is 4-20 mA,
LOW is 0-10 V
“[511] AnIn1 Fc” = Process Ref;
set AnIn1 as reference signal input
“[512] AnIn1 Setup” = 4-20mA;
set AnIn1 for a current reference signal
“[513A] AnIn1 Enabl” = DigIn;
set AnIn1 to be active when DigIn3 is HIGH
“[514] AnIn2 Fc” = Process Ref;
set AnIn2 as reference signal input
“[515] AnIn2 Setup” = 0-10V;
set AnIn2 for a voltage reference signal
“[516A] AnIn2 Enabl” = !DigIn;
set AnIn2 to be active when DigIn3 is LOW
“[523] DigIn3=AnIn”;
set DIgIn3 as input fot selection of AI reference
Subtracting analogue inputs
Example 2: Subtract two signals
Signal on AnIn1 = 8 V
Signal on AnIn2 = 4 V
[511] AnIn1 Function = Process Ref.
[512] AnIn1 Setup = 0-10 V
[5134] AnIn1 Function Min = Min (0 rpm)
[5136] AnIn1 Function Max = Max (1500 rpm)
[5138] AnIn1 Operation = Add+
[514] AnIn2 Function = Process Ref.
[515] AnIn2 Setup = 0-10 V
[5164] AnIn2 Function Min = Min (0 rpm)
[5166] AnIn2 Function Max = Max (1500 rpm)
[5168] AnIn2 Operation = Sub-
Default:
Process Ref
Off
0
Input is not active
Max Speed 1
The input acts as an upper speed limit.
Max Torque 2
The input acts as an upper torque limit.
Process Val 3
The input value equals the actual process
value (feedback) and is compared to the
reference signal (set point) by the PID
controller, or can be used to display and
view the actual process value.
Process Ref 4
Reference value is set for control in
process units, see Process Source [321]
and Process Unit [322].
Min Speed 5
The input acts as a lower speed limit.
